My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

The Kan Extension Seminar Returns

Posted by Emily Riehl

In early 2014, the nn-Category Café hosted the Kan Extension Seminar, a graduate reading course in category theory modeled after Daniel Kan’s eponymous reading course in algebraic topology at MIT. My experience with the seminar, described here, was overwhelming positive, so I am delighted to announce that we’re back. Alexander Campbell, Brendan Fong, and I are organizing “Kan II” in early 2017 and we are currently soliciting applications for seminar participants.

Our plan is to read the following eight papers between mid January and mid May:

Freyd, Algebra valued functors in general and tensor products in particular

Beck, Distributive laws

Kelly, On the operads of J.P. May

Kelly, Structures defined by finite limits in the enriched context, I

Kelly, On Clubs and data-type constructors

Lack and Rosicky, Notions of Lawvere theory

Berger, Mellies, and Weber, Monads with arities and their associated theories

We are seeking eight participants who will read and engage with all of the papers as well as prepare an oral presentation on one of them, followed by a blog post to be published here, on the nn-Category Café. The course will conclude with a series of short public expository lectures given, by those able to attend, on July 16 in conjunction with the 2017 International Category Theory Conference at the University of British Columbia in Vancouver.

More details, including information about how to apply, can be found on the seminar website or by contacting any of the three organizers. Applications are due November 30th. I hope you will help us spread the word by passing this message along to those who might be interested.

Re: The Kan Extension Seminar returns

Terrific! As a participant in the first Kan Extension Seminar, I can’t recommend the experience enough to anybody considering applying! I very much look forward to the public discussions here, which should be invigorating given the very nice selection of papers and the top-notch organizers.
